Firmer Chisels

Firmer chisels have thick, rectangular blades for heavy chopping and mortise cleaning.  They are the workhorses of carpentry and construction.

What are firmer chisels used for?
Firmer chisels are traditional woodworking tools used for general-purpose cutting, paring, and shaping of wood. Their thicker, rectangular cross-section makes them strong and durable, ideal for both light chopping and controlled hand work in joinery, cabinetry, and carpentry.

How do firmer chisels differ from other types of chisels?
Firmer chisels have a straight-sided, thick blade that offers greater strength and stability compared to bevel-edged or paring chisels. While they may not reach into tight corners like bevel-edge chisels, they excel at precise straight cuts and heavier material removal, especially when struck with a mallet.

How do I use and maintain firmer chisels effectively?

• Keep the edge sharp using sharpening stones or honing systems at a bevel angle of around 25°–30°

• Use a wooden or nylon mallet to avoid damaging the handle during striking

• Ideal for cutting mortises, trimming tenons, or squaring corners in larger joinery

• Store in a tool roll or box with edge protection to preserve sharpness and safety
  With proper maintenance, firmer chisels provide clean, controlled cuts and long-lasting durability for daily woodworking tasks.
